	The High Intensity and Energy (HIE) upgrade to the on-line isotope separation facility (ISOLDE) facility at CERN is currently in the process of being commissioned. The very tight space available between the superconducting acceleration cavities and a challenging specification led to the design of a compact 'diagnostic box' with a number of insertable instruments on a common vacuum chamber. The box was conceived in partnership with the engineering firm AVS and produced as a completed assembly in industry. 14 diagnostic boxes have been installed and are now operational. This paper will describe the design, the construction and first results from operation of these HIE ISOLDE diagnostic boxes.

The High Intensity and Energy (HIE) upgrade to the on-line isotope separation facility (ISOLDE) facility at CERN is currently in the process of being commissioned. The very tight space available between the superconducting acceleration cavities and a challenging specification led to the design of a compact 'diagnostic box' with a number of insertable instruments on a common vacuum chamber.

Electron lenses (e-lens) have been proposed and used to mitigate several issues related to beam dynamics in high current synchrotrons. A hollow electron lens system is presently under development as part of the collimation upgrade for the high luminosity up-grade of LHC. Moreover, at GSI an electron lens system also is proposed for space charge compensation in the SIS-18 synchrotron to decrease the tune spread and allow for the high intensities at the future FAIR facility. For effective operation, a very precise alignment is necessary between the ion beam and the low energy electron beam. For the e-lens at CERN a beam diagnostics setup based on an intersecting gas sheet and the observation of beam induced fluorescence (BIF) is under development within a collaboration between CERN, Cockcroft Institute and GSI. In this paper we give an account of recent preparatory experiments performed at the Cockcroft Institute's gas curtain experimental setup with the aim to find the optimum way of distinguishing between the signals due to the low energy electron beam and the relativistic proton beam.
